The rapid development of the femtosecond laser has revolutionized materials processing
due to its unique characteristics of ultrashort pulse width and extremely high peak intensity …

The unique characteristics of ultrafast lasers have rapidly revolutionized materials
processing after their first demonstration in 1987. The ultrashort pulse width of the laser …

When a femtosecond laser pulse is focused inside a transparent material, the optical
intensity in the focal volume can become high enough to induce permanent structural …

We report on the joining of dissimilar transparent materials based on localized melting and
resolidification of the materials only around the focal volume due to nonlinear absorption of …

Direct laser write of volume Bragg gratings with diffraction efficiency (absolute)∼ 90% is
demonstrated using Gauss-Bessel laser beams in fused silica glass. Axial multiplexing of∼ …

Focusing ultrafast laser pulses inside a transparent material induces localized permanent
structural modifications. Using these permanent structural modifications, one can produce …

Multilevel phase-type diffractive lenses were fabricated by translating a filament of a
femtosecond laser pulse into three-dimensional space inside synthesized silica. The profile …

This paper provides an overview of femtosecond laser microfabrication in polymeric
materials, with emphasis on lab‐on‐chip applications. Due to the nonlinear interaction of …

To our knowledge, we report on the first demonstration of Type A VBGs inscribed in silver-
containing phosphate glasses by femtosecond laser writing. The gratings are inscribed …

In this study, we demonstrate the elongated Type I modifications in fused silica with an axial
length> 50 µm. Such extended longitudinal dimensions were obtained by deep focusing …
